I'm still getting used to raising baby bettas, but do the babies need to have and air pump in the tank with them?
I was told that they don't need to have one cause at this age their developing that organ that lets them breathe oxygen and an air pump will just get them sick and they'll die, then I was told that at this age they will be dependent on the air in the water in the tank while they are developing the organ. I just don't know what or who to believe and listen to. My babies are only about 2 to 3 weeks old and still very small.I would show pictures, bu t the pictures won't show up.

if you can find one a sponge filters a good idea

but nothing else any current and ut will kill them
